I just got back from CES.
LG had the most impressive display I have ever seen at the show. They built a video wall using their passive 3D LCD TVs about 10 high by 30 wide running custom 3D material. It used the passive glasses, of course, which were comfortable and lightwieght, especially considering how inexpensively they were probably made.
People were so impressed, they actually clapped at the end of the clip. Smiles were on everyone's faces. They had all kinds of flyouts from the screen including baseballs, cars, boats, rocks, and more. There was a lot of depth into the screen, too, even with their "universe" scene. The overall look was very 3D, and high quality. I did not see scan lines breaks that you usually see with passive 3D, I presume because they had so many monitors. With the huge size, it was very immersive.
If this didn't sell some people on their passive 3D TV system, I don't know what would.
They also had 3D playing on their three OLED panels. You could see scan lines, but I don't think they were quite as obtrusive as what is seen on the LCDs. Perhaps the pixel structure is a bit tighter. I didn't see any ghosting or flickering. It looked very good.
I think LG proved that 3D can be very entertaining, and with their passive system, the glasses are almost a non-issue.
